Designers Kenneth Cobonpue and Albrecht Birkner have come up with a novel use for bamboo: building a car.

The two have come up with a concept called the Phoenix Roadster, the world's first biodegradable car. It was built in just 10 days, is only 153 inches long, and, in addition to bamboo, is made from steel, rattan, and nylon. It's currently on display at the Imagine and Innovation in Milan.

The outer "skin" of the vehicle is designed to last around five to 10 years, the average lifespan of a car. But if owners wish to keep their vehicle for longer, a new skin can be purchased and fit onto the chassis.
